A group of Bernard Madoff’s broke victims auctioned off beloved prints by Picasso and Chagall, a stunning 70-carat diamond-and-emerald necklace and other items in Florida last night to recoup at least some of the money he swindled from them.

“I think we’re helping people,” said buyer Stacey Giulianti, 41, who placed the glittering necklace around the neck of his beautiful brunette wife, Christina, after bidding $75,000 at Kodner Galleries in Dania Beach.

“It’s a very sad situation, but I feel this is a ‘win-win,’ ” said Christina, referring to the necklace’s anonymous seller getting some cash after losing a fortune to Madoff’s Ponzi scheme — and to her husband getting a bargain price.

Featuring a 16-carat emerald, the necklace had a pre-sale estimate of $150,000. Kodner’s staff said that on the open market, it could sell for $400,000.

Last night’s auction, which drew a well-heeled crowd that arrived in a slew of Mercedes, featured 75 items placed by five Florida-based Madoff victims, all of whom were anonymous. In addition to prints by Picasso and Chagall, there was a large collection of sterling-silver flatware, a Chinese ivory elephant-tusk carving of a bridge, and other odds and ends.

Kodner first auctioned items from a single Madoff victim several months ago, netting the seller $30,000, and plans to stage another such sale in July.

“When I go into these homes, these homes of these victims, I’m so sad,” said auction-house owner Ross Kodner. “I go into houses that are 15,000 to 20,000 square feet that have to be liquidated so they can go to smaller quarters. Thank God I can provide some small assistance.”

“These people need money to live.”

That money was less than hoped for, in some cases.

The Picasso, a print of the painting “Recordant el Doctor Reventos,” sold to an anonymous buyer on the phone from Westchester County for $5,400.

Sy Lemler, a retiree from New York, said, “I don’t feel sorry” for the sellers.

“They were greedy,” he said. “I would have never invested, never, with Madoff, ever.”
